To all whom it may concern: -Be it known that I, THOMAS Invnm Po'r- 'TER, a citizen ofthe United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented certain new and useful Improvements in Coin-Delivering Machines; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, and to the figures and letters of reference marked thereon.

This invention relates to coin delivering machines and has for its objects to provide an exceedingly simple and compact machine with which different sums ofmoney may be paid rapidly and'accurately by the manipulation of suitable keys, the keys themselves bein preferably utilized to actuate the ejectmg mechanism, whereby the employment of separate operating mechanism, such as an operatin lever may be avoided. Another object o the invention is to so group the coin holders or receptacles and the oper-' ating keys that the lateral dimensions of the machine may be reduced and at the same time the capacity increased to such an extent that coins of all denominations may be handled and delivery made of a large aggregate sum or of any fractional part of the same.

0 Referring to the accompanying drawm igure 1 is a top plan view of a machine embodying the present improvements, a portion of the top plate and rear coin chute being removed;

Fig. 2 is a sectional side elevation, the upper portion of the view bein taken substantially on the line 2' -2' of lower portion on the line 2-2 of Fig. 1 so asto showthe key levers, shafts and e ecting mechanism operated thereby;

V Fig. 3 is a front elevation showing the levers, shafts and ejecting mechanism mounted in the frame of the machine, but omitting the cover plates and coin holders;

Fig. 4.- 1s a top plan view of the parts shown 'in Fig. 3;

Fi '5 is a sectional plan view taken substantlally on the broken line 55 of Fig. 2 to illustrate one group of keys, its shaft and the ejecting mechanismpperated thereby;

Fig. 6 is a similar view on substantlally the dotted. lines of Fig. 2 and lllustrate ing another ig. 1, and the.

ou of ke s a .fa'rts 0 erated thereby? i p Fig. 7 is a similar view taken substantially on the line 77 of Fig. 2 to illustrate the th1rd group of keys and parts operated thereby;

Fig. 8 is a perspective view with parts in section showing the-relative positions and movement of. theparts operated by one key of the group; c

' Fig. 9 is a perspective View of the entire machine;

Fig. 10 is a plan viewof the keyboard arranged as shown in Fig. 4; and

Fig. 11 is a similar view showing a modification of the keyboard, whereby coins. of different denominations may be delivered.

Like letters of reference in the several figures indicate the same parts.

In accordance with the resent invention and in order to reduce as ar as practicable the lateral dimensions of the machine and at the same time increase its capacity for rapidly delivering a gross sum or fractional parts thereof, a grouping and banking arrangement of the coin holders or receptacles and of the manipulating keys is resorted to; thus, referring to Fig. 9, it will be seen that the coin holders or receptacles 46, 47, and 48, are arranged in groups and banked rows, one row being in front of and at a lower level than the other row. The operating keys 33 are arranged in similar banks and rows, there being in the machine illustrated three rows of flat keys 33, the rows being arranged at different levels and one in front-of the other. The keys have flat surfaces for y the operators fingers, in this respect corresponding closely in form and appearance to the keys of a piano keyboard. This arrangement and form permits of the simultaneous operation of two keys with one fin r and of. any combination 0 one or more the fingers and thumb of one hand. It seeys with cures a speed of operation far in excess of any keyboard now in use. The order of arr'angement of the keys for ejecting from the various coin stacks is such as to facilitate this rapid and simultaneous operation, the

arrangement being of the lowest denomination at one end and progressing to the highest at the other end. he arrangement is such that combinations may be made for paying any amount up to the full capacity of the machine. Each key-is meted on the forwardly rojecting end of a lever 32, and each row of keys referably corresponds to a group of coin ho ders or receptacles.

The groups and banks of .coin holders are preferably located at, the left hand sideof the machine and the keys at the right hand side of the machine; thus, the operator may manipulate the keys with the fingersv of the right hand and receive theejected coins in the left hand which is held beneath the central bottom discharge opening of a chute 51 which conducts the coins from all of thereceptacles to the single point of delivery. lin carrying out the scheme of the arrangement the mechanism is mounted on a base 11 from which frame plates 12, 13, 14 and 15, pro- Mounted in suitable bearings in the plates 12, 15, referred to, are shafts 20, 21, and 22, each shaft being formed by a central shaft member and a plurality of sleeves surrounding the same or telescoped together and constituting in effect a group ofshaft members,

each of which is capable of independent angular movement about a common axis. The key levers 32 of each group of keys are connected'respectively with one of the members of each shaft; thus, referring to Fig. 5, it will be seen that the key levers 32 are connected with the shaft 20 and sleeves 23 and 24, respectively, while in Fig.- 6 the key levers are connected respectively with the shaft-21 and sleeves 25, 26 and 27 while in Fig. 7, the key levers are connected with the shaft 22 and sleeves or shaft members 29, 30 and '31, respectively.

At the opposite ends of the shaft from the key levers the shaft members are provided with operating arms; thus, the membars 20, 23 and 24 carry operating arms 34, the shaft member 24 having two operating arms 34 thereon, as shown in Fig. 5, for a purpose to'be presently explained. In Figs.

and '6 it will be seen that corresponding arms 34 are connected with the shaft members 22, 29, 30, and 31, and 21, 25, 26, 27 and 28. The arms 34 secured to shaft members 22, 29, 30 and 31 project forwardly, while the arms 34 connected with the members of the other two shafts project rearwardly. All of the arms 34 are connected with upwardly extending links 35, and the latter are jointed to the short arms of hell crank levers pivotally mounted on the shafts 37 and 39, the arrangement being such that upon the depression of any key its shaft member will be oscillated and the bell crank lever wtth aeearoar which its operating arm is connected will be turned on 1ts axis in av direction to cause itsupwardly projecting longer arm' to swing toward the front of the machine. The said upwardly projecting arms ofthe bell crank levers 36 and 38 constitute devices which directly engage and operate the ejectors,

thus, the connection between the keys and the 'ejectors is practically a direct connection involving but few parts, and those parts of such construction that the leverage of the key levers 32 may be utilized to-the best ad- I vantage so as to secure the requisite throw of the ejectors with a minimum key movement. 1

By reference toFigs. 1 and 2 it will be seen that there is secured to the plates 13, 14 and 15, transversely extending supporting members 41, 41' and 42, which carry the coin holders or receptacles '46, 47, and 48,

, and said holders and supporting members 41,

41 and 42 are slotted on the under side to form guideways for the ejectors 43 and 44. Said ejectors are in the form of bars adapted to slide in their guideways toward and from the frontof the machine and in their forward movements to intersect the bottom of the coin holders, engage the rear edges of coins in. said holders and advance the same until released from the supporting portion of the holders, when they drop down through the chute to the point of delivery. Each ejector bar 43 and 44 is provided with a bearing for the rounded upper end or head 45 of one of the bell crank levers 36 or 38,

whereby the bars will be reciprocated when the bell crank levers are oscillated.

In the preferred construction the ejector bars are mounted on the ends of the bell crank levers so as to be capable of a pivotal or oscillatory movement thereon, and springs; v

60 are provided which hold the forward ends of the bars up against their guiding surfaces, but at the same time permit said forward ends to be depressed by the weight of the stackof coins in the holder. Inasmuch as very light springs may be employed there is but slight frictional resistance durin the return movement. The operation 0 the mechanism will be readily understood from an inspection of Fig. 8, wherein it will be seen that. the spring 60 connects the rear end of the ejector bar 44 with the bell crank lever 36, at a point below the end of the lever and consequently said spring tends to hold the forward end of the bar up in its channel and in position to engage the lower-. most coin in the holder 48. Assuming that the ejector bar has been advanced to the position shown in dotted lines by'the depression of the key 33, and that the coin has been discharged, the remainingcoins in the holder will depress the forward end'of the e ector bar to the position shown in dotted hues, and. theonly resistance to the due to the slight friction caused by the spring 60, 'holdmg the forward end of the ejector bar up against the bottom coin. ThlS construction permits the parts to operate very freely and conse uently very light springs, such as 61 may e rovld'ed for re-' turning the parts to norma position ready for another eration.

The coins scharged from the upper bank or groups 46 and 47 of the coin holders drop into a chute 49 which has a bottom extension 50 communicating with the chute 51 into which the coins from the lower or front.

, ing, as shown in Fig. 9 beneath which a suitable tray may be placed, or as in the preferred construction, the operator may place his hand for the reception of the coins.

The movements of the operating bell crank levers 36 and 38 are limited in both directions by stops formed preferably by rods 40 mounted in the plates 13, 14 and 15 between which rods said bell cranks areoscillated in the operation of the machine.

Each group of keys, it will be noted, is connected with the shaft members of a single shaft, and said members are connected with the ejecting mechanism for a group of coin holders; thus, with three shafts each composed of a plurality of shaft members movable angularly about the same axis and carried by the same bearings in the frame of the machine, it becomes possible to provide for ejecting a large number of coins and combinations of coins so as to permit of the delivery of practically any fractional value within the capacity of the machine, but in order to deliver change with certain specified coins therein, it is sometimes desirable to have one key operate two ejectors; for example, in Fig. 5 one key operates two ejectors, each of which will deliver two pennies, and the group of coin holders controlled by the mechanism of Fig. 5 will therefore be adapted to hold pennies exclusively, three of the coin holders being adapted to eject two pennies each, and one to eject a single penny at each operation. The group of keys illustrated in'Fig. 6 is adapted to effect the delivery of fifty-cent pieces, twenty-five cent pieces, ten cent pieces and nickels, there being five keys, two of which, however, will deliver ten cent pieces or dimes. The coin holders are therefore arranged one to hold nickels, two to hold dimes, one to hold twenty-five cent pieces and one fifty-cent pieces.

The group of keys illustrated in Fig. 7, four in number, are adapted to control the delivery of five dollar pieces, four dollars, two dollars and one dollar, respectively, and

the coin holdersare, therefore, correspond- I I claim as new and desire to secure by Letingly arranged,'the four dollar key being connected with two ejectors, each adapted to discharge two one dollar coins, and the two dollar key being connected with one i ejector adapted to discharge two one dollar COIIIS.

Obviously, while the arrangement of the keys preferred is shown in Fig. 10, other arrangements are within the scope of the invention, and as shown in Fig. 11 an arrangement is provided, which, instead. of' delivering five dollars and four dollars, a single key is rovided for delivering two dollars and fity cents, which key is connected with two key levers which will effect the operation of the proper ejectors for ejecting and delivering this amount.

It Wlll be understood that any of the ejectors may be arranged to discharge one, two or more coins at each operation, for to accomplish this result it is only necessary to drop the bottom or supporting surface of the holders down to a point where the desired number of coins at the bottom of the stack 'will be in position for the ejector to cooperate therewith. This construction is'a common one in the art and for it no claim is made herein.

Having thus described my invention what ters Patent of the United States, is: a
